bei sudo mdadm --assemble --scan rattern die Platten kurz und es erscheint auch ein Array. Jedoch ist dies nur 533MB gross und enthaelt nur irgend welche Config Dateien.
Vorweg die verwendeten Festplatten habe ich zur Sicherheit mit einem USB Adapter geclont... Im NAS waren 3x 6TB Platten drin. Da ich aber nur eine 6TB und eine 8 TB HDD hier hatte hab ich eine der beiden 6 TB auf die 8 TB Platte geclont.
Bitte um Hilfe. Bin nicht ganz unerfahren aber auch nicht total fit in Sachen Linux.
